Tori Spelling's worst date ever involved her throwing up in a saucepan.

The former 'Beverly Hills 90210' actress - who is pregnant with her third child with husband Dean McDermott - vomited her "guts out" in a restaurant kitchen after feeling sick throughout her first date with an up and coming actor many years ago.

She explained: "He called and asked if I was free to go to dinner Friday at 8pm. I said yes. I was feeling sick. Actually, the room started spinning at this point. When suddenly his dimples started floating up on his forehead I knew I had to find a bathroom and quick.

"I excused myself from the riveting conversation and bolted for the bathroom. I just kept telling myself, 'Don't make eye contact with the restaurant patrons, or their amazingly delicious meals, and walk straight.' "

Despite her best intentions, Tori - the daughter of late TV and film producer Aaron Spelling - didn't make it to the bathroom in time and vomited into a "massive copper saucepan" a waiter held out for her.

Writing on her official blog, she said: "Then, I saw it, the door. The bathroom door! Five more Steps and I'd be safely in a bathroom stall where I could puke my guts out. I pushed open the door, and walked right into the kitchen.

"The whole kitchen staff looked up at me. I put my hands up to cover my mouth, but I knew it was too late. A waiter rushed over with a massive copper saucepan where I proceeded to vomit the four rum and cokes and the cliff bar I had had at 11am into it."
